Abstract
Evaluation of seasonal infestation on long duration pigeonpea genotypes against pod borer (Helicoverpa armigera Hubner) and field conditions was executed at Oilseeds Research Farm of C. S. Azad university of Agriculture & Technology, Kanpur during 2012-13. One hundred germplasm of pigeonpea (Cajanus cajan) along with two checks i.e. T-17 (susceptible check) and Bahar (resistant check) were evaluated following Augmented Design. The test material was grouped into highly resistant (HR), resistant (R), susceptible (S) and highly susceptible (HS) categories based on the pod infestation. The results revealed that 79, 10, 08 and 03 genotypes were classified into highly resistant (HR), resistant (R), susceptible (S) and highly susceptible (HS) having up to 20%, >20-30%, >30-40% and above 40% pod infestation due to pod borer (H. armigera), respectively.
